EXTENSION-COVER LOOSE-LEAF BINDER.

Specification of Letters Patent.

Patented Feb. 24;, 1920*.

' Application filed May 12, 1917. Serial No. 168,142.

-To all whom it may concern:

and State of California, have invented a new and useful Extension-Cover LooseLeaf Binder, of. which the following is a specification.

This invention relates to devices of the character designed to detachably hold a series of leaves or sheets and also includes the leaves themselves. I

More particularly the invention in some of its aspects relates to that type of binder in which the leaves may be offset from one another, the offsetting being employed to indicate the live or active accounts of any particular period of time, such ofi'setting being employed extensively for instance, in machine bookkeeping.

With binders of prior construction having a plurality of posts or pins rigidlyconnected to the cover members it has been necessary to make a perforation-in each leaf for each post, thus entailing considerable time and labor in making the perforations binder constructed in accordance and also waste of the paper. Besides this a large number of perforations is objectionable in machine. bookkeeping, since the leaves are run through an adding machine and, owing to the large number of perforations, are apt .to be torn when running through the machine.

An object of this device is to minimize the tendency to tearing of the leaves when they are run through an adding machine or the like. 7 7

Another object isto facilitate the fasteningdand unfastening of the leaves in the bin er. 1

Another object is to produce a device of this character of which the leaves have their edges cut or indented to a minimum degree so that the leaves will passthrough an adding machine or the like with little liability of becoming torn during the operation.

Other ob ects and advantages will appear in the subjoined detail description.

Theaccompanying drawings illustrate the invention:

Figure 1 is an elevation of the back oi-a with this invention, leaves bein shown in alinement with one another in t e binder.

9 are posts 12 which in the instance Fig. 2 is a sectional elevation of the binder in Fig. 1, some of the leaves being oii'set and the intermediate post being in its swung out of their binding positions.

Fig. 4 is a sectional elevation on line indicated by m m*, Fig. 1.

F i 5 is an enlarged sectional detail on line mdicated by w w Fig. 1.

Fig. 6 is a fragmentary plan View of one end of one of the binding strips showing the notch for reccivingthe post.

Fig. 7 is a reduced view of one of the leaves in Figs. 1 and 2.

There are provided covers respectively comprising binding strips 1, 2 and cover members 3, 4i hinged at 5, 6 to the respective binding strips. The binding strips 1, 2 may be of any suitable construction, but preferably as shown in the drawings, are

rectangular tubes 7 having plugs inserted in their ends, the plugs for the binding strips 1 being indicated at 8 and those for the binding strip 2 being indicated at 9.

Pivoted at 10 in notches 11 of the lugs sliown in the drawings are of sectional construction so that by providing difierent numbers of'the sections the posts may be lengthened or shortened as desired so as to change the capacity of the binder. The notches 11 do not extend entirely through the plugs 9 so as to leave shoulders 13 adapted to prevent the posts 12 from swinging outward and downward beyond positions in planes substantially coinciding with the plane of the binding strip 2. 1

The plugs 8 are provided with notches 14 extending from side to side of the plugs and designed-to accommodate the posts 12 when said posts are swung into their binding positions in Fig. 2. The notches 14 are counterbored at 1 5, the counterbores beginnin in sufli'ciently far from the ends of the bin ing strip so as to leave shoulders 16 at the outer ends of the notches. The posts 12 are screwthreaded at 17 to receive nuts 18 which are provided with externally reduced portions 19 substantially fitting the notches 14 and which are provided, with inclined faces 20 adjacent the reduced ortions 19, said faces 20 fitting the counter res 15. Thus when the osts are inthe binding positions with the aces 20 of the nuts seated in the coun- .5 terbores 15, the shoulders 16 will prevent the nuts from swinging away from the notches 14. The-reduced portions 19 ofthe nuts protect the threads the 'posts agamst contacting with the plugs 8 and consequently 10 prevent injury to said threads.

Between the covers of the binder are clamped, when the posts 12 are m bmdmg osition and the nuts 18 are in the counterores 15,'loose leaves 21, the edges of sand 15 leaves resting against the posts and being held in alinement thereby. The clamping actionof the posts 12 and nuts 18 "holdin the covers toward one another of itsel would tend to hold the leaves 21 in place, but if desired the leaves may be provided with notches 22, see Fig. 7 at opposite edges of each leaf, said notches .fitting the posts so that when the posts are in the notches of the leaves the leaves cannot possibly be disp1aced from their bound positions as in The binding strip 2 is provided with a recess or groove 23 and pivoted at 24 in said groove 'is a post 25, .which may be formed in sections as shown,said post being capable of being swung into vertical position relative to the binding strip as in Fig.

1 or intothe groove 23 as in Figs. 2 and 3.

When the leaves 21 are all in alinement with 85 one another and the post 25 is in binding position as in Fig. 1 said post fits into the notches 22 of the leaves so as to aid in retaining said leaves in their bound positions.

. Thus it is clear that when the leaves are 40 alined' as in Fig. 1 they are held and alined at one edge by one of the end posts 12 and are held. and alined at the other edge by the intermediate post 25.

From-.the foregoing it is seen that the post 25 is movable into and out of binding position.

When the intermediate post 25 is folded 6%. down into the groove 23 as in Fig.. 2 some ...'fo'f the leaves 21 may-be offset from the others as said post will be out of the way of the leaves, and it is clear'that some of the leaves are engaged andalined by one ofthe posts 12 and other of-sthe leaves-are engaged and alined by the other post 12.

When the post 25 is. in its binding osi tion as in Fig. 1 it passes through a per oration 26 in the binding strip 1.

In practice considering the'binder parts to be in the position shown in Fig. 1, if it 00 be desired to. take out or insert'leaves in the binder. the'nuts 18 will be turned to loosen them and then the, posts 12 will be swung v outward from the notches 14 thus releasing the binding strip 1. The cover 1, 3 will then 6 be removed and the desiredi-number of sheets mounted post' positioned 'of said covers having a perforation to reremoved or inserted and the cover may then be replaced by a reversal'of the operations just noted.

When for any reason it is desired to offset some of the leaves 21 from others of the leaves as, for example, to indicate which leaves have been run through an adding machine or the like, the leaves 21 will be raised sufliciently to allow the post 25 to be swung into the groove 23, whereupon an of the leaves desired may be ofiset as s own in It is' sometimes desirable to retain the leaves in their ofi'set positions for an in} terval of time when the binder is closed and in'such event the cover 1, 3 will be placed in binding position and the posts 12 swung into binding positions just the same as de scribed above when the leaves were in alinement with one another.

After checking up the accounts on the offset leaves, sald leaves are once more alined with the other leaves and the post 25 will then be swung into binding position as in Fig. 1 so as to aid in retaining said leaves.

I claim: a

.1. In combination, covers, one of said covers having a groove, means closable' into the groove and movable therefrom to hold. leaves alined with one another nearer one edge of the covers than the opposite edge.-

2. In combination, covers, a collapsibly a substantial dis-. tance from the edges of the covers, said post being movable into and out'of binding posi-' tion, and means independent of said post to hold the covers toward one another to clamp leaves therebetween.

3. In combination, covers, posts hinged to one of the covers near its opposite edges, a

third post hinged to one of the covers intermediate of the first named posts, the other ceive the third post and having notches to receive the end posts, and means to hold the end posts in said notches.

4. In combination. covers, posts hingedto one of the covers, there being notches in the other cover and said notches being counterbored, leaves between the covers having notches closely fitting the posts, and nuts on the posts fitting into the counter'bor'es when theposts are in the notches In combinationy'covem, leaves between the covers having notches in their opposite edges, posts connected with the covers to fit the notches'of different leaves when said leaves are offset from one another. and another post connected with one of the covers covers having a groove, and the other cover a perforation, means 'closable into the groove and movable therefrom and engageable with the perforation to engage leaves placed between the covers.

7 In combination, covers, leaves between the covers having notches in their opposite edges, means adapted to engage the "notches When the leaves are in alinementwith one another, and means cooperating with the last-named. means when one of the leaves is 10 ofl'set from others of said leaves to engage one of the notches of the offset leaf..
